1. A bundle of tubular and/or rod-shaped glass articles, comprising:
a longest dimension of the glass articles extending in a first direction of a Cartesian coordinate system, the longest dimension defining a length of the glass articles;
a plurality of layers (NL) of the glass articles, wherein the glass articles in each layer of the plurality of layers are arranged side by side in a second direction of the Cartesian coordinate system, the second direction being perpendicular to the first direction, and wherein the plurality of layers are arranged side by side in a third direction of the Cartesian coordinate system, the third direction being perpendicular to the first and second directions; and
a thread-like element is wrapped at least partially around at least two of the glass articles in at least one layer of the plurality of layers so that the two glass articles are spaced apart, the thread-like element being twisted from fibers or strips of material or being a string, line or cord,
wherein the thread-like element has a minimum cross section (ct), wherein the thread-like element is wrapped around the glass articles at a plurality of different spaced positions (nt) along the length of the glass articles, wherein the plurality of different spaced positions and the minimum cross section are selected according to:

wherein l corresponds to the length of the glass articles in mm,
wherein do corresponds to an outer diameter of the glass articles in mm, and
wherein tw corresponds to a wall thickness of the glass articles in mm, the wall thickness of a rod-shaped article being equal to one half of the outer diameter, and wherein the space between two tubular and/or rod-shaped glass articles is less than 16% of the outer dimension of the tubular and/or rod-shaped glass articles, and wherein the thread-like element is fastened to form a releasable knot with an adhesive force between about 0.1 and 4.0 N, wherein the adhesive force is the force necessary to untie the knot.
